Automated viscometer performs high-throughput analysis

By Chemical Engineering |

RheoSense

The automatic VROC initium Model II viscometer (photo) is now available for viscosity characterization of any solvent-based solutions. VROC (viscometer-rheometer-on-a-chip) technology combines microfluidic and MEMS (micro-electro-mechanical systems) technologies to measure dynamic viscosity over a wide range of operation. High-throughput and timely measurements are now easier to perform and more productive, says the company. Accurate and precise viscosity measurement is assured with self-diagnosis, leaving no uncertainty. The viscometer can measure intrinsic viscosity and true viscosity, even at high shear rates up to 148,000/s with minimal sample volume. Sample recovery after measurement helps save samples for further analysis. The system performs viscosity analysis of the sample for the process and quality control, or for product development. Samples placed in a vial rack or 96-well plate are automatically picked up and tested. Larger payloads of solvent bottles allow measurement of 96 samples with a single charge of solvents. — RheoSense, Inc., San Ramon, Calif.
